TIRE BIM.

Application filed January 7, 1927. Serial Nc. 159,556.

` The present invention relates to improvements in solid rims for automobile tires and is applicable either to rims of the demountable type. or to rims formed as a permanent part of disc or wire wheels, an object of the invention being to provide a construction which will permit of themcunting of the tire with the inner tube therein, without the necessity of prying the same on at one point and then gradually forcing the restkof the tire in place, but will enable the whole tire to be slid into place in substantially flat rela tion with respect to the rim. `I-leretofore it has been necessary to first completely engage the valve stem with the inner tube in its opening in the rim, and thereupon the tire was gradually forced into place about the rim.

It is proposed, in the present embodiment of the invention, to provide an improved tube-valve receiving structure incorporated in the rim and which will guide the tubevalve into place as the whole tire is pressed upon the rim equally at all points.

A further obj ect is to provide such a structure which will not weaken the rim and which may be incorporated therein in a simple practical manner. y

With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto and the invention will be finally pointed out in the claims.

In the drawings:

Fig. l is a side elevation of a portion of a rim according to the present embodiment of the invention. y i

Fig. 2 is a sectional view of the rim showing the same mounted upon a work table, supporting it horizontally` and showing, in dotted lines, the tire partially engaged upon the rim.

Fig. 3 is an enlarged transverse lsectional view of the rim showing the tire in place thereon. n

Fig. 4 is a plan view of the valve-stem receiving portion of the rim.

Similar reference characters indicate cor responding parts throughout the several ligures of the drawings.

Referring to the drawings, the improved rim cnnstruction, according to the present af inventien, ecmnrisee circular solid rim 10 providedinthe usual manner at one edge with a groove 11 adapted to receive the tire retaining split spring ring 12, `as shown in Fig. 3, and provided at its other edge with a backing iiange 13.

As shown in Fig. 2, the rim may be mounted upon a stand or other suitable support, the illustration showing the stand as comprising a center support 14 having a horizontal .circular plate 15 mounted thereon and provided at its edge with a `stepped iiange 1.6 including a reduced diameter portion adjacent the upper surface of the plate, this flange adapted to receive the rimV as shown with one of the ribs l--usually providedupon the inner surface of the rim- H resting upon the shoulder of the ange to thereby rigidly support the rim in horizontal position. This particular type of stand enables the rim to be reversed so that the grooved edge 11 will abut the shoulder of the flange 16, and in this position the tire may be removed from the rim without the use of tools in the case of a new or undamaged tire, and in the case of a tire adhering to the rim for any cause, the same would haie to be loosened by the use of a suitable too The rim is provided at one point with an elongated slot 18 extending from the center to a. point inwardly removed from the grooved edge 11, this slot being preferably slightly flanged as shown in Fig. 3. Within the slot there is secured the valve-stein guiding and receiving member 19, according to the present embodiment of the invention. This member may be secured in the slot in any suitable manner, or the structure may, if desired, be formed integrally with the rim. As shown. the member is provided at its periphery with a flange 2O spaced from the upper edge and which abuts the lower edge of the flanged edge of the opening` 18, p

As shown in Fig. 2, the tire 27 is engaged mpontlie npper edge of the rim in flntwise t relation-that is, ell portions of the tiren-re eolnnllj,7 engaged'at the saine time,` the valvestem 28 of the inner tube 29 being preseed inwardly so that its outer end is inwardly7 of the base of the tire, and is positionednt n point in line with the member 19. As the tire ir-'forced `downwvnrdly uponthe *ri-rn, the `wll'veesten'l 28 `enters the groove 2li thereby positioninf?lr the stein against rdisplnoement sothat it 1s guidedto the valve-stem receiving opening into which it is `automaticfilly projected throngh-the elasticity of the inner tnbe.` "It `will he nnderetoodthat While Jche innertnbe is partially inflated in -the nena] manner, the -presenrelis not snh as to pre- Aventpressing in ofthe valve-stem.
